"The Million-Year-Old Teen-ager"
*Garn, a caveboy, and Akkuru, his giant enemy, are frozen in suspended animation by a prehistoric glacier, and revived in modern times. When Akkuru menaces the town of Smedleyville where Garn has become a student at the local high school, the townspeople believe Garn responsible for the giant's rampages. Garn's girlfriend, Penny Randall, calls in the Teen Titans who team up with Garn to defeat Akkuru thus vindicating the teenage caveboy. *Source: Official Teen Titans Index #1 - Published by ICG
